problem with MARC::File::XML on RH 5 64bits

Hello,

I try to install Koha on a RH server, that was previously on RH 4 (Koha 
worked fine), and that has just be upgraded to a RH 5 (and Koha don't 
work at all).
RH being 64 bits, on a Dell server.

I have reinstalled yaz, and zebra and get a nasty error on Koha.
Investigating, it seems I have a problem with M::F::X :
> [root@so-crm-catalogue MARC-XML-0.88]# make test

Any idea welcomed..., as google is not my friend on this.
